Request to add Bikram Sambat, a calendar system, in Alternate Calendar plugin.
Comment 1 Fushan Wen 2025-02-19 00:02:42 UTC 
The libicu libraray doesn't support Bikram Sambat, so the alternate calendar plugin that depends on it needs to implement its own calendar system. Would you like to contribute?

I wish I could, but I lack programming skills. I can try to find someone who would like to contribute.

I have been maintaining a Bikram Sambat calendar plasmoid for KDE Plasma:
https://store.kde.org/p/2303034
I'd be interested in helping add Bikram Sambat support to KDE's Alternate Calendar framework.
One thing to note is that Bikram Sambat is generally data-driven rather than purely mathematical. Month lengths vary between years, and official calendar data is only available for a limited range. My current implementation supports dates up to 2100 BS (≈ 2043/2044 AD) using published calendar tables; beyond that, additional official data would need to be incorporated.

If KDE is open to this approach, I'd be happy to help with an upstream implementation.
